Saturday, 3/14/15, marks a once-in-a-century Pi Day, corresponding to the first four digits of 3.1415.

If you really want to celebrate in mathematical style, take it out a few more places and clink your glasses at 9:26:53 a.m. (3.141592653). Those nine digits are more than enough for most applications requiring pi.
